JOHN ODEN MORRIS, OF RICHMOND, VIRGINIA.

GENERATOR FOR STEAM-BOILER FURNACES.

SPECIFICATION forming part of Letters Patent No. 631,120, dated August15, 1899.

Application filed April 14,1899.

f0 (ZZZ whom, it may concern:

Be it known that I, JOHN ODEN MORRIS, a citizen of the United States,residing at'Richmond, in the county of Henri'coand State of Virginia,have invented new and useful Improvements in Generators for Steam-BoilerFurnaces, of which the following is a specification.

My inven tion relates to generators for steamboiler furnaces; and itsobject is to provide improved means whereby steam from the exhaust of anengine or live steam from a steamboiler mixed with air can be suppliedto the furnace underneath the grate for the purpose of promotingcombustion of the fuel.

The object of the invention is to provide an improved construction ofthe same which shall possess superior advantages with respect toefficiency in operation.

The invention consists in the novel construction and combination ofparts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation showing myimprovements applied to a locomotive and tender. Fig. 2 is a detailfront elevation of the locomotive. Fig. 3 is a front elevation of astationary boiler provided with my improvements. Fig.

at is a longitudinal section of the same. Fig. 5 is a detail perspectiveview of the perforated head located in the generator. Fig. 6 is alongitudinal section of the coupling connecting the generator-pipe withthe steam-supply Referring now to Figs. Land 2, the reference-numeral 1designatesa locomotive, and

2 the tender thereof, of any ordinary or suitable construction.Oonnected with the exhaust of the cylinders of the engine is a pipe 3,which extends rearwardly to the tender and is connected with a coil 4:,located in the waterbox of the tender for the purpose of heating thefeed-water contained therein.

The numeral 5 designates a pipe connected with the pipe 3 and leading tothe generator hereinafter described. This generator is the same inconstruction and operation whether applied to an engine-boiler or aboiler for heating or other purposes, so I will therefore describe thesame as used in connection with the boilers shown in Figs. 3 and 4..Referring now to said figures, the reference-nu- Serial No. 713,010. (Nomodel.)

meral 6 designates the ash-pit door, hinged to the front of the furnace,as usual, and provided with a rectangular opening through which thegenerator 7 passes and extends under the grate. This generator consistsof a rectangular box open at both ends, and the front end, which islocated outside said door, is provided with a flaring mouth or end 8.When the furnace is provided with two ashpit doors, then two generatorsare employed; but as they are identical in construction and operation adescription of one will suffice for both. Located in said generator is arotatable paddle-wheel, comprising the shaft 9 and paddles 10, thelatter of which are formed with openings 12 for insuring a perfectadmixture of the steam and air fed to the ashpit underneath the grate.

The numeral 13 designates a horizontal pipe located in said generatorand provided with a transverse pipe 14;, having perforated heads 15. Theouter end of the pipes 13 is connected with a vertical pipe 17 by acoupling constructed as follows: The numeral 18 designates a nipplescrew-threaded internally and externally and formed with an angularportion 19, with which a wrench is adapted to be engaged for the purposeof screwing the same in a section 21, having a flange 22 and formed withan interior shoulder 23. Bolted to this section 21is an upper section25, formed with a boss 25, the edge of which is sharpened and bites intoa washer 25 seated on a flange 26 at the lower end of apipe 26, which isconnected with the steam-boiler.

The operation is as follows: Steam from the boilers is admitted to thegenerator through the pipes connected therewith, which steam escapingthrough the perforated heads will impinge against the paddle-wheel andturning the same will tend to create a vacuum in the generator and willthus cause air to be drawn into the same and mixing with the steam willbe fed to the ash-pit and grate, and thus insure complete combustion ofthe fuel.

When the invention is used in connection with steam-boilers for runninga locomotive or other engine, I prefer to supply the generator withsteam from the exhaust of the cylinders instead of directly from theboiler, as such steam is mixed with the oil or other lubricant of thecylinders,which, mixing with the steam and air, will add still furtherto the efficiency of the device in promoting combustion of the fuel.

Suitable valves or cocks are to be employed wherever found desirable ornecessary.

Having thus fully described my invention, what I claim is- 1. In asteam-boiler furnace, the combination with the ash-pit door having anopening therein, the generator, the steam-supply pipe extending into thegenerator and the pipe connected therewith by a swivel or flexibleconnection, of the transverse pipe connected with said supply-pipe andlocated in said generator, the perforated head connected therewith andthe rotatable wheel provided with blades havingopenin gs therein,substantially as described.

2. In a steam-boiler furnace, the combination with the ash-pit doorhaving an opening therein, the generator, the steam-supply pipeextending into the generator, the pipe connected therewith by a flexibleconnection and the exhaust-pipe extending from the cylinder andconnected with said swivel connection, of the transverse pipe connectedwith said supply-pipe and located in said generator, the perforated headconnected therewith and the rotatable wheel provided with blades havingopenings therein, substantially as de- 30 scribed.

the pipe connected therewith provided with a peripheral rirn, the uppersection connected therewith provided wi th a boss having a sharpenededge, the lower section bolted to said upper section having an enlargedupper end, the 40 packing, the screw-threaded nipple and the supply-pipeconnected therewith, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing wit- 45
